Perhaps you should try some spelling variations:
ng decrease » a decrease (Expand Search), we decrease (Expand Search), gy decreased (Expand Search)
nm decrease » a decrease (Expand Search), we decrease (Expand Search), gy decreased (Expand Search)
nn decrease » a decrease (Expand Search), mean decrease (Expand Search), gy decreased (Expand Search)
50 nn » 50 ns (Expand Search), 50 ng (Expand Search), 50 n (Expand Search)
5 ng » 5 mg (Expand Search), 5 g (Expand Search), 5 kg (Expand Search)
5 nm » 5 mm (Expand Search), 5 cm (Expand Search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "(((( 50 _ decrease ) OR ((( 5 ng decrease ) OR ( 5 nm decrease ))))) OR ( 50 nn decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (((( 50 _ decrease ) OR ((( 5 ng decrease ) OR ( 5 nm decrease ))))) OR ( 50 nn decrease ))*.
